MENLO PARK, CALIF. -- Facebook says a bug in its system led to 6 million users’ contact information being inadvertently exposed.

The social media company said yesterday that a bug led to some contact information — such as email addresses or phone numbers — to be uploaded by other users.

The problem arose when a Facebook user clicked on the “Download Your Information” tool. Because of the bug, the user may have been provided with additional email addresses or telephone numbers for their contacts or people with whom they have some connection.

Facebook says it has fixed the problem and is in the process of notifying affected users via email.
